[aprssig] Increased Diode Efficiency

For anyone ever frustrated by the 0.7 to 1V voltage drop across rectifiers
in low voltage circuits, there is now a chip that can drive nearly-zero
resistance MOSfets to do the rectification with nearly zero voltage loss
(and hence, no need for heatsinks):

Linear Technology has released a new IC making possible to achieve a
perfect bridge rectifier :

I donno whether they can work as distribution diodes too, (isolation
diodes for batteries etc,) but it looks promising for higher power 12v
stuff.
